Embodiment Construction

[0017] Refer to the attached figure 1 and 3 , as the best embodiment of the present invention, it discloses a flat airbag water seal, including a water seal body 1, a water seal pressure plate 2 and connecting bolts 3, the water seal body 1 is a hollow cavity 8 Oval, one side of the water seal body 1 is provided with an inflation joint 4 for communicating with the hollow cavity 8, and the connecting bolt 3 passes through the water seal pressure plate 2, the water seal body 1 and the gate seat plate 6 to seal the water The body 1 is fixed on the gate seat plate 6 , and the connecting bolts 3 and the water seal pressure plate 2 are arranged on one side of the water seal body 1 . In this way, a flat airbag structure is formed as a whole. When in use, the flat airbag is installed on the gate seat plate 6 with a water seal pressure plate 2 and connecting bolts 3; There is a suitable gap between them, which will not affect the opening and closing of the gate; when the present inve...

Abstract

The invention discloses a flat balloon water seal, comprising a water seal body, a water seal pressing plate and a connecting bolt, wherein the water seal body is elliptical and has a hollow cavity, and an air filling connector communicated with the hollow cavity is arranged at one side of the water seal body; the connecting bolt passes through the water seal pressing plate, the water seal body and a gate seat plate, so that the water seal body is fixed to the gate seat plate; and a lip portion located above the hollow cavity is arranged on the water seal body. In use, a flat balloon is mounted on the gate seat plate by using the water seal pressing plate and the connecting bolt; under a normal operating condition, the water seal is flat and has an appropriate gap with a component having relative motion without affecting opening and closing of the gate; and when the flat balloon water seal is put into use, the hollow cavity is filled with air by an air compressor via the air filling connector, and the water seal body dilates under the action of the air pressure and is in contact with the gate and a built-in part to form a water stop surface, thereby achieving a water stop effect.

Description

technical field [0001] The invention relates to the technical field of water seals, in particular to a flat air bag water seal which is installed at the corresponding position of the gate, can be quickly put into use in an emergency state, and can adapt to complex water sealing conditions. The pressure deformation is in contact with the relevant parts that need to be water-stopped to achieve the purpose of water-stopping. Background technique [0002] The water sealing device is one of the main components of the water sealing of the gate, and its reliability and effectiveness directly affect the function of the gate. In the gate water seal device, P, J, and Ω type water seals are widely used, relying on a certain pre-compression and sealing water pressure to cling to the water-stop seat surface of the gate embedded parts with good flatness to achieve water-stop Reliable, to ensure that the water leakage of the gate meets the requirements. For example, the publication numbe...
